Climate change has been a perplexing problem for years. Casey's research into the Sun's activity, which began almost a decade ago, resulted in discovery of a solar cycle that is now reversing from its global warming phase to that of dangerous global cooling for the next 30 years or more. This new cold climate will dramatically impact the world's citizens.

Deniers of climate change sometimes quip that claims about global warming are more about political science than climate science.

It will be a social and political disaster of the first order.

Most historians study the smallest slivers of time, emphasizing specific dates, individuals, and documents.

How would looking at the full span of time change the way we perceive the universe, the earth, and our very existence? These were the questions David Christian set out to answer when he created the field of "Big History", the most exciting new approach to understanding where we have been, where we are, and where we are going.
